Page lifecycle:
- ProcessMemory now tracks (PhysicalAddress, count) pairs for each
allocation (up to 16). destroy_process iterates and frees all
pages back to the pool. No more permanent page leaks on exit/fault.
- RequestPages re-adds MemoryRegion entries so ReleasePages works.
Release test un-ignored, passes.
- RequestPages: VA allocation moved after pool allocation succeeds,
preventing VA leak on OOM.
IPC hardening:
- WaitQueue overflow (>16 waiters): returns WouldBlock error instead
of silently dropping the thread. Thread is not blocked if enqueue
fails.
- debug_assert on pending_messages[sender].take() — invariant that
a sender in wait queue must have a pending message.
Scheduler:
- remove() now clears current thread if the removed thread was
current on its core.
- add() asserts push succeeded; bitmap bit only set if thread was
actually added to RunList.
Cleanup:
- Priority::DEFAULT replaces Priority::new(16).unwrap() in
spawn_thread and spawn_thread_in.
36 kernel tests pass, 0 ignored.
